1
Understand the structure and function of elastic cartilage: Elastic cartilage is a type of cartilage that provides flexibility and strength. It is found in structures like the external ear and epiglottis.
Identify the primary components of elastic cartilage: Elastic cartilage is primarily composed of elastic fibers, which allow it to stretch and return to its original shape. It also contains chondrocytes embedded in a matrix.
Eliminate incorrect options: Adipocytes are fat cells and are not found in cartilage. Osteocytes are bone cells and are specific to bone tissue. Collagen type I fibers are found in dense connective tissues and bone, not elastic cartilage.
Focus on the correct option: Elastic fibers are the defining feature of elastic cartilage, providing its characteristic flexibility and resilience.
Conclude that the primary component of elastic cartilage is elastic fibers, as they are essential for its function and structure.
